Century plant (<em>Agave celsii</em>)

All plants need light in order to grow, but different species require different amounts of light. Remember that some rooms in your house will be sunnier than others, depending on which way the windows face. Keep this in mind when selecting a spot for each plant, to ensure that it will grow properly.


Plants receive direct sunlight all day long. This is the ideal spot for species that thrive in full sun. Plants that require bright light should be protected from direct sun between 10 a.m. and 5 p.m. in summer, however. A south-facing exposure is not a good place for plants that require little light, especially from April to October.


Plants receive direct sunlight in the morning and plenty of indirect light the rest of the day. Plants that thrive in bright light will do well in this setting year-round. Plants that require indirect light should be moved slightly back from the window in summer.


Plants receive direct sunlight in the late afternoon and plenty of indirect light in the morning. The sun is stronger and warmer here than in east-facing windows. This is a good spot for plants that tolerate a few hours' sun a day.


Plants receive plenty of indirect light in summer, but less light from November to February. Plants that prefer indirect light will do well here year-round. Some plants that require bright light may adapt to this spot in summer.
